CAPE CANAVERAL, Fla. -- After being rotated from a horizontal to vertical position, the canister that contains the Raffaello multi-purpose logistics module, or MPLM, for the STS-135 mission, is lowered onto a transportation vehicle in the Canister Rotation Facility at NASA's Kennedy Space Center in Florida. Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim are targeted to lift off on space shuttle Atlantis July 8, taking with them the MPLM packed with supplies, logistics and spare parts to the International Space Station. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing spacecraft and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.
